Surface of earth is in the troposphere range. The troposphere is the nearest layer to the earth.
No. The asthenosphere is within the earth and so by definition cannot include the water contained on the surface or in the atmosphere.

Over 99% of the mass of the earth's atmosphere is contained in two layers: the troposphere and the stratosphere. Most of the earth's atmosphere (80 to 90%) is found in the troposphere, the atmospheric layer where we live. This layer, where the earth's weather occurs, is within about 12 km (7 miles) of the earth's surface.

No. The early Earth's atmosphere contained a lot of ammonia, for example.
how did water from the earth's surface get into the atmosphere
Gravity.
the atmosphere of earth weighs approximately 5×1018 kg, 3/4 of which is within 11 miles of the earth's surface.
The gravitational pull keeps the Earth's atmosphere close to the surface...
Troposphere is the lowest layer of the atmosphere, which is adjacent to the earth's surface.
To the extent that the sun warms the atmosphere, and varying temperatures within the atmosphere are the basis of winds, yes.
